IPC: C07F9/09
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To obtain a mixture having an adjusted composition ratio by treating a mixture of a phosphoric monoester and a phosphoric diester with a metal oxide and water and adsorbing only the phosphoric monoester. SOLUTION: A metal oxide such as silicon oxide (silica gel) or alumina and water, preferably ion-exchanged water or distilled water are made to exist in a mixture of a phosphoric monoester and a phosphoric diester and the amount of water in the mixture is controlled to regulate the composition ratio of the phosphoric monoester and the phosphoric diester. The activity of a metal oxide is lowered when it contains water, a phosphoric monoester is specifically adsorbed on a metal oxide in the presence of water and a phosphoric diester is hardly adsorbed. Consequently the composition of the mixture can be simply adjusted and isolation and purification by a column chromatography, etc., is not required. The mixture is useful for an adhesive, a surfactant, etc.
